hello thanks for looking at my post, i have a 91 crx si w/b16a and my charging voltage is 12.8 @idel and if i rev it up a lil it jumps to 14.5 is this ok?i have a couple subwoofers and at night the audio set up draws a lot of power and dims the lights while iam driving.

 

That seems to be normal. My rex sits a little above 13 at idle and jumps up to 14.x when i tap the throttle. I am running an average sized amp to 4 component speakers. Also I read in my shop manual that the crx also has a circuit that drops the output voltage under certain conditions. I believe it had something to do with economy.

 

is there a way to bypass that circuit, so its always charging 14+?

 

its just that during idle it really doesnt spin the alt enough. The easiest way to go about it is to put a larger crank pulley like a b20 to overdrive it or just raise the idle to 1,200 or so

 

Im pretty sure that it only is in effect at cruising speeds.

 

Get yourself a capacitor, or a optima battery, or a larger AMP alt.

i did all that, i have a 160 amp alt, a red top and a 2 farad cap, and it still dims the lights all crazy, i have 2 w7's and a 1000/1 and a 300/4 amp...

 

i had a buddy check his charging system and it read 14.5 while at idel....do you guys have that reading ? his was a stock 89

 

bump

 

does anyone know there charging voltage @ idel?

 

 

your dimming lights isnt because of your voltage level it has to do with your amprage...how do u have everything wired? if you dont have i wired right you can have 12 batteries and it wont do ****

 

I would do the big three.
Should help ALOT!.

i have it wired from the battery, someone told me that if you have it connectd from the battery the eld dosent see the load?is this true?i did put 0 guage on my battery and on the ground and the alt, i dont have one on the transmission i will add a 0 guage ground there..thanks for the help guys

 

bump

 

No offense meant, but, CLEAN YOUR BAY.....GO TO THE CAR WASH AND CLEAN THAT UP!!

gross. I would worry about that before my lights dimming while trying to out techno the volkswagon at the stoplight.....

 

verry true i need to clean it up it looks like $hit.. and techno is for quers i just ''bump'' the country

hahaha that's going into my sig.


get a deep cycle battery. ones for boats and stuff, they draw the power out differently or something. i had a celica with one and also had 4, 15's in it once and the lights never dimmed ever.

 

 

help....

 

nice subs... what i did in my van to stop the dimming of the lights (two phoenix gold octain R 10d subs in a ported box pushin 400+watts per sub, wired in parallel VC so it's runnin @ 2 ohm, plus a 4ch amp to the speakers) was i added a kinetic battery to my charging system. it's the equivalent to 200+ farads. never had a problem since. and trust me, my stuff would dim WAY down when i was drivin at night. i also upgraded my alt power wire from 10g to 4g. helped alot

 

yea i might have to do that...add 1 more battery
